The blur is what sells the speed. Without it this is just a spin that happens to travel — try commenting the filter out to see how much work it is doing. It loops here so you can watch it; in a product it plays a single time on arrival and holds — that is the default.
The class is wm wm-speed-roll — the first half is the marker the trigger and reduced-motion rules hook into, the second is the effect.
